We have a program installed on all clients that uses MS SQL Server 2000 installed on a w2k box. Every three times each user log on to the program, Active Directory locks the user account. SQL uses Windows authentication mode. Probably it is some GPO var? does anyone knows which one???? TIA Mauricio Fernández S.
